Conduction, Convection, and Advection are means of transferring heat energy in a system. Consider the given
statements:
1. Conduction is the molecule-to-molecule transfer of heat energy as it diffuses through a substance.
2. Convection takes place when the physical mixing involves a strong horizontal motion.
3. Convective motions are possible only in liquids and gases.
4. When vertical motion dominates, the term advection applies.
Which of the statements given above are correct?
  • a)
    1 and 3 only

Conduction is the molecule-to-molecule transfer of heat energy as it diffuses through a substance.
Convection takes place when the physical mixing involves a strong vertical motion. It is possible in only in liquids and gases.
When horizontal motion dominates, the term advection applies.
Hence only first and third statements are correct.

The correct statements are 1 and 3 only.

1. Conduction is the molecule-to-molecule transfer of heat energy as it diffuses through a substance.
This statement is correct. Conduction is the process of heat transfer that occurs within a substance or between substances in direct contact. In conduction, heat energy is transferred from higher energy molecules to lower energy molecules through molecular collisions. This transfer occurs due to the temperature difference between the molecules.

2. Convection takes place when the physical mixing involves a strong horizontal motion.
This statement is incorrect. Convection is the process of heat transfer that occurs in fluids (liquids and gases) due to the combined effects of conduction and fluid motion. In convection, heat energy is transferred through the bulk movement of the fluid itself. It can occur in both horizontal and vertical directions, depending on the specific situation. Therefore, convection is not limited to strong horizontal motion.

3. Convective motions are possible only in liquids and gases.
This statement is correct. Convective motions occur in fluids, which include both liquids and gases. In fluids, the transfer of heat energy through convection is facilitated by the fluid's ability to flow and move. Solids, on the other hand, do not have the ability to flow and therefore do not exhibit convective heat transfer.

4. When vertical motion dominates, the term advection applies.
This statement is incorrect. Advection refers to the process of heat transfer due to the bulk movement of a fluid, similar to convection. However, advection does not specifically refer to vertical motion dominating over horizontal motion. It simply describes the transport of heat energy by the fluid's motion, regardless of its direction. Therefore, this statement is not accurate.

In conclusion, the correct statements are 1 and 3 only. Conduction involves molecule-to-molecule transfer of heat energy, and convective motions are possible only in liquids and gases.
